Why do these aspects of data change with each other?
When two aspects of your data seem related, you can tell a story about how they interact. The fancy name for this is “correlation”. If one measure goes up, the other goes up too. If one goes down, the other goes down. In other cases, they might interact as opposites (when one goes up, the other goes down). You need to be careful not to guess about reasons for the interaction, but noticing the relationship itself can be a good story that connects things people otherwise don’t think about together.
